Essential plant nutrients supplied by soil are categorized into macro-nutrients and micro-nutrients based on the quantity required. Macro-nutrients are mineral elements needed by plants in relatively large quantities for proper growth, structure, and metabolic processes; examples include Nitrogen and Phosphorus. Micro-nutrients are mineral elements meeded by plants in very small or trace quantities to support enzymatic activities; examples include Iron and Zinc. Both types of nutrients are vital for healthy plant development.
